COFFEE-POT.

SPECIFICATION forming part of Letters Patent No. 268,061, dated November 28, 1882.

Application filed July 25, 1882. (No model.)

To all whom it may concern Be it known that I, JOHN W. WEAKLEY, of Bond Hill, Hamilton county, Ohio, haveinveuted certain new and usefulImprovementsin Goffee-Pots, of which the following is a specification.

This invention pertains to that class of coffeepots designed and constructed to return to the decoction the aromatic vapors arising therefrom by condensingthem against a cool surface above the vessel containing the decoction; and it consists of a novel arrangementof the condensing apparatus, as hereinafter set forth and claimed.

In the accompanying drawings, Figure l is a vertical section, and Fig. 2 a plan, of the device.

A is the main vessel, constructed as usual andprovided with a handle and lidded spout.

O is a deep top section with rim B, fitting well down Within the main vessel A, extending to bottom of vessel A,and containing a hole, a, therein,opposite the mouth of the spout, out of which to pour the coffee.

G is a diaphragm across the upper portion of the top section, 0, forming a water-chamber, F, above it. A hole, L, in the roof or lid K communicates direct with this chamber.

11 is a central aperture in the diaphragm O.

J is a tube'forming conduit fromthe aperture H to the interior of the chamber F. This conduit J rises Well up. into the chamber F, and then descends to a point near the diaphragm F, as shown,so as to form avva-terseal in an obvious manner.

I is a valve in the tube J, normally closing the aperture H. A stop-wire prevents the valve lifting too'far.

D is a diaphragm across the top section, at a pointbelow the diaphragm G, forming between the two diaphragms the condensing-chamberO. The aperture in the diaphragm D placesthe chamber 0 in communication with the main vessel A.

In operation the coflf'ee decoction occupies the main vessel A. Cold water is placed in the water-chamberFthrough hole L. This Water keepsthe condensing-plate G cool, and is prevented from leaving the chamber F by the valve I.' The chamber 0 forms a non-couducting division between the main vessel A and the condensing-plate G,and serves to protect the latter from the direct action of heat previous to the vaporization of any of the liquid in the main vessel. The chamber 0, containing air much cooler than the contents of the main vessel, serves to keep the diaphragm D somewhat cool, so thatit will act as a preliminary condensing-plate. Vapors unoondensed by the plate D will finally fill the chamber 0, be condensed by contact with water-cooled plate G, and run back into the main vessel A through aperture E. Should vapor reach a comparatively high'tension, it will lift the valve I and escape into the water in the vessel F. In construction the parts may be arranged to separate for more convenient cleaning.

I claim as my invention 1. The combination, substantially as set forth, of main chamber A, air-chamber (J, watenchamber F, and valve I.

2. The combination, substantially as set forth, otmain vessel A, top section, 0, sealrim B, diaphragms D and G, top K, with hole L, and seal-conduit J.

3. The combination, substantially as set forth, of main vessel A,seal-rim B, diaphragms D and G, top K, with hole L, and valve I.
